This triaxial orthogonal magnetic probe, by employing an intersecting arrangement, can reduce the overall spatial volume, but it is difficult to control the perpendicularity of the horizontal and vertical circuit boards. Summary of the Invention

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The purpose of this invention is to provide an orthogonal welding fixture for use in the fabrication of a triaxial orthogonal magnetic probe, so as to improve the perpendicularity between the horizontal circuit board and the vertical circuit board of the triaxial orthogonal magnetic probe.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1 , Figure 2 This embodiment provides an orthogonal welding fixture for use in the fabrication of a triaxial orthogonal magnetic probe, which includes a horizontal circuit board 21 and a vertical circuit board 22.

[0033] The orthogonal welding fixture includes a first mounting base 11, a second mounting base 12, and clamping structures. The first mounting base 11 has a first mounting groove 13 for placing a horizontal circuit board 21. The second mounting base 12 has a second mounting groove 14 for placing a vertical circuit board 22. There are multiple clamping structures, namely a first clamping structure 15 and a second clamping structure 16. Both the first clamping structure 15 and the second clamping structure 16 include clamping blocks. The clamping blocks of the first clamping structure 15 are used to clamp and fix the horizontal circuit board 21 within the first mounting groove 13, and the clamping blocks of the second clamping structure 16 are used to clamp and fix the vertical circuit board 22 within the second mounting groove 14. The first mounting base 11 and the second mounting base 12 are capable of relative sliding, allowing the horizontal circuit board 21 and the vertical circuit board 22 to translate relative to each other while always remaining perpendicular.

[0034] The working principle of the orthogonal welding fixture in this embodiment is as follows:

[0035] After placing the horizontal circuit board 21 into the first mounting slot 13, the horizontal circuit board 21 is positioned by contact between its edge and the wall of the first mounting slot 13. Similarly, after placing the vertical circuit board 22 into the second mounting slot 14, the vertical circuit board 22 is positioned by contact between its edge and the wall of the second mounting slot 14. After positioning, multiple clamping structures are used to press the horizontal circuit board 21 and the vertical circuit board 22 together, ensuring that the horizontal circuit board 21 is fixed on the first mounting base 11 and the vertical circuit board 22 is fixed on the second mounting base 12. Then, by sliding the first mounting base 11 and the second mounting base 12 relative to each other, the distance between the horizontal circuit board 21 and the vertical circuit board 22 can be adjusted, facilitating the connection of the horizontal circuit board 21 and the vertical circuit board 22 into one unit through operations such as insertion and soldering. Specifically, in this embodiment, one of the horizontal circuit board 21 and the vertical circuit board 22 is provided with a pin, and the other is provided with a slot. When the horizontal circuit board 21 and the vertical circuit board 22 are close to each other, the pin is inserted into the slot to achieve the insertion and connection of the horizontal circuit board 21 and the vertical circuit board 22. Afterwards, the pin pads 23 on the pins can be soldered to the slot pads 24 on the slots to improve the stability of the connection. During the relative sliding of the first mounting base 11 and the second mounting base 12, the horizontal circuit board 21 and the vertical circuit board 22 only undergo relative translation, not relative rotation, and always remain relatively perpendicular to each other to improve the perpendicularity of the horizontal and vertical circuit boards of the triaxial orthogonal magnetic probe.

[0036] The clamping structure can be either a rigid clamping structure or an elastic clamping structure. In this embodiment, the clamping structure is preferably an elastic clamping structure, which takes advantage of its easy elastic deformation to facilitate the adjustment and fixation of the horizontal circuit board 21 or the vertical circuit board 22. The elastic deformation of the clamping structure can be accomplished by the pressure block, by other components, or by both.

[0037] When the elastic deformation is completed by the pressure block, the pressure block is an elastic pressure block to apply elastic pressure to the horizontal circuit board 21 or the vertical circuit board 22. The elastic pressure block here can be a spring, a spring, or other types of components.

[0038] When elastic deformation is accomplished by other components, the clamping structure also includes an elastic element that applies elastic pressure to the pressure block toward the horizontal circuit board 21 or the vertical circuit board 22. This elastic element can be a sheet spring, a spring, or other types of components.

[0039] Elastic blocks and elastic elements can be used together to increase the amount of elastic deformation.

[0040] Since the orthogonal welding fixture is not a disposable fixture but needs to be used repeatedly, the clamping structure must be able to avoid the horizontal circuit board 21 and the vertical circuit board 22 when replacing the horizontal circuit board 21 and the vertical circuit board 22.

[0041] As one possible example, in this embodiment, the pressure block is rotatably mounted on the first mounting base 11 to avoid the horizontal circuit board 21 when it enters or leaves the first mounting slot 13. And / or, the pressure block is rotatably mounted on the second mounting base 12 to avoid the vertical circuit board 22 when it enters or leaves the second mounting slot 14.

[0042] However, the actual implementation is not limited to this. For example, the pressure block is detachably mounted on the first mounting base 11 to avoid the horizontal circuit board 21 when it enters or leaves the first mounting slot 13. And / or, the pressure block is detachably mounted on the second mounting base 12 to avoid the vertical circuit board 22 when it enters or leaves the second mounting slot 14.

[0043] For example, the screw shank passes through the pressure block and is threaded into the first mounting base 11 or the second mounting base 12. The screw head is used to limit the position of the pressure block to prevent it from detaching from the screw shank. If the screw head is pressed against the pressure block, the pressure block cannot rotate, and the pressure block can be removed by unscrewing the screw. In this case, the pressure block is detachably mounted. If the screw head is not pressed against the pressure block, i.e., the pressure block can rotate, the pressure block can also be removed by unscrewing the screw. In this case, the pressure block can be considered as either rotatable or detachable mounted.

[0044] There are various ways to connect the first mounting base 11 and the second mounting base 12 so that they can slide relative to each other, and those skilled in the art can choose according to actual needs.

[0045] As a possible example, in this embodiment, the orthogonal welding fixture further includes a guide post 17, which enables relative sliding between the first mounting base 11 and the second mounting base 12. The guide post 17 slides through at least one of the first mounting base 11 and the second mounting base 12. Relative sliding between the first mounting base 11 and the second mounting base 12 can be achieved by sliding either the first mounting base 11 or the second mounting base 12 along the guide post 17.

[0046] Specifically, in this embodiment, the guide post 17 is fixed to the first mounting base 11 and slides through the second mounting base 12. Depending on the actual needs, those skilled in the art can also fix the guide post 17 to the second mounting base 12 and slide through the first mounting base 11. In this embodiment, by engaging the guide post 17 with the shaft hole of the second mounting base 12, the perpendicularity of the first mounting base 11 and the second mounting base 12 can be ensured, thereby ensuring the perpendicularity of the horizontal circuit board 21 and the vertical circuit board 22.

[0047] As can be seen from the above, when the first mounting base 11 and the second mounting base 12 slide relative to each other, the horizontal circuit board 21 and the vertical circuit board 22 translate relative to each other, that is, the horizontal circuit board 21 and the vertical circuit board 22 do not rotate relative to each other.

[0048] Therefore, when all the guide posts 17 are cylindrical rods, there should be at least two guide posts 17 to prevent the first mounting seat 11 from rotating relative to the second mounting seat 12.

[0049] When the guide post 17 includes a non-cylindrical rod (for example, the cross-section of the guide post 17 is rectangular), only one non-cylindrical rod is needed to ensure that the first mounting seat 11 and the second mounting seat 12 will not rotate relative to each other. Of course, in order to improve the overall reliability of the orthogonal welding fixture, multiple non-cylindrical rods can also be provided to guide the relative sliding of the first mounting seat 11 and the second mounting seat 12.

[0050] As a possible example, in this embodiment, both the horizontal circuit board 21 and the vertical circuit board 22 correspond to at least two clamping structures. The two clamping structures corresponding to the horizontal circuit board 21 respectively clamp the two ends of the horizontal circuit board 21, and the two clamping structures corresponding to the vertical circuit board 22 respectively clamp the two ends of the vertical circuit board 22.

[0051] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
